2 Claims. (Cl. 15-320) This invention relates to improvements in cleaning apparatus and more particularly to means for cleaning Venetian blinds, walls and other surf aces.

One of the objects thereof is to provide a simple, eiiicient and inexpensive hand sprayer gun designed to be used for the purpose of brushing with a fluid spraying action the surface to be cleaned in such a manner that, by moving the cleaning means therein about and over various points of the surface to be cleaned all parts thereof can be given a thorough cleansing.

A further object thereof is to provide a hand sprayer gun with a rotary brush with which is effectively associated fluid spraying and iiuid suction means for the purpose of causing the brush to spread a cleansing iluid over the surface it soeurs as Well as for the purpose of exhausting out of the sprayer gun the particles of., fluid with its content of dirt and impurities sol as to remove the moisture deposited upon the surface being cleaned.

'AAnother object thereof is to provide a hand operated and controlled sprayer gun with the parts so shaped, arranged and constructed that cleansing uid will be sprayed continuously over the periphery of a rotating brush, and moisture from the surface already cleaned by the spraying iiuid continuously sucked out through the rotary brush to a point of convenient discharge from the gun.

A still further object thereof is to provide a hand sprayer and suction gun with novel brushing means in the form of va detachable interchangeable brush head adapting the gun for use in the cleansing of various diierent surfaces in some way part of or connected with a building.

In carrying out the foregoing objects I have designed a hand held and hand operated and controlled outiit that carries a suitable pumping medium for both injecting a cleansing fluid thereinto as well as drawing out said fluid by a suction action after the same shall have come in contact with the surface being cleansed. To this end there is disclosed a system of fluid injecting ducts in both the sprayer gun and brush in the same parts of the gun and brush attachment, establishing a desirable cycle or circula tion of fluid to and from the surface being cleansed with the View of continuously supplying fresh cleansing fluid to the discharge end of the gun as fast as the dirt loosening and dirt soaked exhaust fluid is drawn out by suction therefrom.

A` further object of this invention is to pr0 vide means for coupling together detachably the sprayer gun and the brush holder in such a manner that a fluid tight seal is maintained effectively between the abutting ends thereof and a continued line of intercommunication maintained at all times both in the sprayer gun and in the brush holder for the passage of cleansing fluid and exhaust fluid therein and thereout.

With the above and other objects in View my invention consists in the combination, arrangement and details of construction disclosed in the drawings and specifications, and then more particularly pointed out in the appended claims.

In the drawings, wherein similar reference E characters designate similar parts throughout the drawings,

Figure 1 is a longitudinal sectional view of one form of my invention,

Figure 2 is a fragmental detail side elevation of the confronting ends of the sprayer ,gun and brush holder in the act of being coupled together,

Figure 3 is a front end elevation of Figure 1` with the brush removed,

Figure 4 is a front elevation of the drum endY of the brush holder in which is housed the rotary brush,

Figure 5 is a cross section taken on line 5-5 of Figure l, and

Figure 6 is a section taken on line 6 6 of Figure 1.

Referring to the drawings, which are merely illustrative of my invention, I disclose the various parts thereof. There is disclosed a sprayer gun comprising as its major length a cylindrical body I 0 formed at its intermediate part with an extension bulge II, and at its outer or for-- ward end preferably with a reduced cylindrical terminal I2. Operatively held in fitted relation abuttingly against the front face of the stem I2 is a gasket I3 of suitable sturdy material. In line with the cylindrical body I0 at its rear end is a slotted handle I4, the slot of which is designated I5. Y Y

Movably seated snuglyin said handle I4 is a lever or trigger 2i, preferably wedge-shaped, having its narrow upper end mounted Jto-swing upon a pivot pin 2t extending in said handle I4. The trigger 2l is `operatively connected to an electric switch, not shown, whereby depression of the trigger 2i will close the switch there--V by completing the circuit to the motor 3l.

The extension bulge II along the lower side ol the intermediate portion of the body III is formed with` several annular internally threaded pro- Yformed with an annular jections l1, I8 and I9, which are adapted to secure the upper end of containers 51, 58 and 59 to the body Ill. The containers 51 and 58 contain a cleaning solution and water respectively.

A passage 2E in the body iB extends through the bulge II and communicates with a tube I which projects downwardly into the container 51.

A passage 21,V also in the bulge Il, communicates between the passage 26 and the opening formed by the annular projection I8. Y extends from the passage 21 downwardly into the container 58.

The containers 51,'53 and 59 form a lower handle for the body Iii, such handle being generally designated as I6.

The passage way 26 communicates with a circular supply duct 29 disposed concentrically of body lil, from which extend circurnierentially spaced apart elongated ducts having their axes parallel to the axis of the body I8 and open as at -`3 out of the annular conical head'SI formed centrally of the washer or closure -jacket I3, to provide sprayer outlets 32. The washer I3 is Y outwardly flaring counter seat or channel 33 around the annular bead 3|, and circumferentially extending series of ducts a have outlets therein which extend inwardly of said body It parallel to the axis thereof.

There is an internal chamber in Figure 1 which houses a motor 31, having a shaft 3S which extends through the chamber H in cylinder body ii! so as to project with its outer end into Washer I3 and dispose its coupling end 3S in the hollow of the annular bead 3l thereof. The shaft 35 is rotatedly held in ball bearing sections 52 and 4l. in which the balls 43 encircle the shaft.

A pump or fan 45 is fixed to the other end of theY shaft 36 and is housed between two chambers S. Rotation of the pump 48 forces air and fluid downwardly through the passage 59, and a tube 53 which extends into the container 59, Vthus forming a suction in one of the'chainbers S, and the passages longitudinal which are directly communicated with the chambers VS, as 45 and 41.

The container 5@ has a volume of nearly the combined volume of the containers 51 and 5S, so that the water and cleaning solution after use are returned to the container 59. Avent` passage 48 in the body lil communicates wtih the'con- ,n3-

rate part of the sprayer gun apparatus designed .5.

for detachment from the latter. It is composed Vof a cylindrical body or stem 6i, which, at its inner end, is formed with an annular peripheral conical bead iiwhic'n'encircles an annular channel or seat 64, which encircles a conical lip 65. Formed at the outer end of the brush holder is a drum of larger diameter than body 5I, formed by meansf of annular iiange 6e which has a rounded periphery, and having a hollow housing dening the interior of the drum.

Formed at the outer part of body 5I, 'which also forms the back. wall of the drum 66 is an outwardly projecting annular conical bead 1d enclosing an interiorV cylindrical seat 15. This bead extends into the rear end of the housing 6 l, and a circumferentially extendingV series of ducts 13 open out therefrom into said housing, which ducts extend axially along the length of the stem BI and also open out of the annular channel' ed thereof* A circumferentially extending series'oi A tube 52 4 ducts are also formed in the periphery of the drum ange 56- such that they follow the round exterior contour thereof and open out of the periphery thereof at one point, and extend down as at 1S radially of body 6I so as to terminate in V13 which open out of the bead 14.

The brush carrier or holder is formed centrally with a bore or chamberl, at the opposite ends of which are lodged ball bearing sections 11 and 18 which confine anti-friction balls 19 around a shaft 8o passing through chamber 15 so as to extend into housing 514 of the drum 66, where it terminates in an anchor head 8| operatively seated centrally in a cylindrical brush back or head vSi. of a size and diameter tosnugly revolve in the drum. Bristles 83 extend over the effective area of the brush back in close proximity. which bristles also project beyond and outside'of the drum SS. The rear face of the brush back 82 is in close proximity to the annular bead-'14 and formed in this brush back concentrically of and opposite directly to and in confronting relation to this bead 14 are concentric rows of through ports $11 which communicate withA the interior of the housing at their inner ends and open out of the brush back at their outerends.

lAs a means of detachably connecting or cou# pling the brush carrier or holder to -the sprayer Y gun proper I disclose the following. At diametrically opposite points of cylindrical body 6I of the brush holder (Figure 2) IA form `suitably shaped cleats 85 having notches 36 therein. Looped links 81 are designed to be carried over so as to be introduced into said notches 86/ ofthe cleats 85. The inner ends of these links` 8,1 at

Y diametrically opposite points of the'body IB of the gun, are pivotally connected at 88 intermediate the length levers 89. The levers 89 are mounted at their inner ends upon pivot pins 90 passing through lugs 9| formed upon the gun body Ii). The levers S2 have handle extensions g2 preferably made of resilient material and arched in contour.

I will now describe the operation ofv the apparatus. The operator takes hold Y of the form, of brush holder shown in Figure l if he wants to clean walls and similar surfaces of a house Vor room. Assuming that first he wants to couple the type of 'brushing device shown in Figure 1, he draws together the confronting ends of the brush holder 6I and outer reduced end I2 of the sprayer gun as illustrated in Figure 2. He hooks on loop links 81 of the gun in the notches 8S of the cleats 85 of the brush holder, and as he takes hold of the lever handles 92 of levers BQ and throws them over completely so that they overlie the exterior surface of the gun cylinder Ii), it will be seen that the rear end of the brush holder is contacted abuttingly With the front end of the gun.

This action couples the' two parts of the cleaning apparatus for joint operation. The operator Vnext takes hold of the gun handle I6 in one hand and may use the other hand to take hold of the finger hold I4 so that with one hand he can steady the machine and position the brush end Y thereof'aga-inst the wall or other flat surface to Y be cleaned and with the other hand he can operate the trigger 2| to control the iiuid in the gun and brush carrier. When he presses the trigger, the switch, not shown, completes the electrical circuit to the motor 31 and the pump 46 is set into operation, creating a suction in one of the chambers S. This suction is created also in the passages 45, 41 and 40a in the body l0, and the passages 12 and 1G in the brush holder body 6|, As the brush is being held against a wall, the suction will also be created in the passages 84 and 13 of the brush holder body 6l and passages 32, 26 and 21 in the body I9. Thus the water in container 58 will be sucked up through the passage 21 and mixed with the cleaning solution, being sucked from container 51, in the passage 25, thence to the circular duct 22 and through the annular outlets 32.

Under suction the cleansing fluid flows through ducts 13 in the brush holder body 3|, around circular duct 12b, and thence out of the outlet ports which open out of the annular bead 14 formed upon the back wall of the drum 66. Suction from the pumping apparatus sucks cleansing fluid directly out of the concentric rows of discharge ports 84 formed centrally of the brush back 82. In the meantime the electrical motor 31 has been in operation to rotate the coupled sections 33 and 80 of the line of shafting from this motor,

due to the coupling end 33 of one shaft tting into the coupling end 38a of the other shaft. This rotates the brush and carries the lines or rows of bristles Ion the brush back in a rotary cycle of movement. This action of the brush receiving the discharged jets of cleansing fluid from I its center as it rotates causes the bristles 93 of the brush, which has been pressed by the operator against the surface to be cleaned, to ccnvey or throw by centrifugal action, the dirt loosened and dirt soaked exhaust fluid churned by the brush over the surface it is desired to Wash and clean by a scouring action, towards the periphery of the cylindrical brush back, where the continuously revolving brush swirls the exhaust dirt soaked uid in the annular groove 69 in the periphery of the drum, from which the exhaust uid is sucked out through the ducts communicating with circular groove 69 (Figure 4), and by way o-f ducts 12, and the ducts 40a in the sprayer gun, which open out into the annular channel into which the annular bead 63 of the brush holder body 6I has been tted, upon intercoupling of the holder and gun. The exhaust fluid, thus passes through the gun and is discharged into circular duct 44 and thence by way of branch ducts 45 to the suction chamber S, and forced into the waste container 59.

I do not mean to confine myself to the exact details of construction disclosed in the drawings and specification, but mean to cover all variations set forth in the appended claims.
